The British government says it wants to rely less on immigrant labour and use more local workers.
However, business groups are concerned the country could miss out on talented employees from other parts of the world.
British Prime Minister David Cameron has unveiled measures he says will significantly reduce the use of immigrant labour.
He's asked the government's Migration Advisory Committee to recommend ways to tighten visa requirements for workers.
"In the past it has been frankly too easy for some businesses to bring in workers from overseas rather than to take the long term decision to train our workforce here at home. Now, we need to do more to change that and that means reducing the demand for migrant labour and that is part of our plan. So I can tell the house today that the home secretary has written to the Migration Advisory Committee asking them to report back on how to significantly reduce work-related migration from outside Europe."
The Prime Minister has been under pressure on the issue after failing to deliver promised cuts to net migration.
Immigration was one of voters' top concerns ahead of last month's national election.
But last month's official figures show the total net migration to Britain reached 318,000 in 2014, the highest level since 2005.
